Image Quality
Part images
and missing
images
Incomplete or missing images. 1
Print damage Creases, curl, cuts, folds, wrinkles, or embossed marks are
visible on the print.
1, 3, 4, 5, 6, 8
Repeat images Refer to offsetting defects and residual image defects. 1, 5
Residual
image
A previous image that was not removed from the photorecep-
tor during the cleaning cycle.
1, 5
Skew A difference in angular alignment between image on the print
and the original document.
7
Skips Loss or stretching of the image, and compression of the
image, in bands across the process direction.
1
Smears Loss or stretching of the image, and compression of the
image, in bands across the process direction.
1, 3
Smudges Darker images across the process direction. 1
Spots Dark spots in the non-image areas of the print. Make a blank
copy
Streaks Lines on the print, in the process direction of the non-image
area.
1, 7, 8
Stretched and
distorted
images
The image on the paper is stretched or distorted. 1
Toner contami-
nation on the
back of prints
Random black spots or marks Make a blank
copy
Uneven den-
sity
Variation in image density across the print. See also non uni-
formity.
1
Unfused prints The toner image on the finished print is not fused to the print
medium.
